Slice the peppers and onions.
Cut bell peppers in half, remove stems, seeds, and white membranes. Slice into thin, even strips about ¼-inch wide. Peel onions, cut in half, and slice into similar-sized strips. Mince the garlic cloves.
TIPKeep slices uniform so everything cooks at the same rate. - saute · ~4 min
Heat the oil and cook the onions.
Place a large skillet over medium-high heat. Add olive oil and let it shimmer. Add sliced onions and cook, stirring occasionally, until they start to soften and turn translucent, about 3 to 4 minutes.
TIPDon't crowd the pan — use your largest skillet to get those nice charred edges. - saute · ~1 min
Add peppers and seasoning.
Add sliced bell peppers to the skillet. Sprinkle with salt, black pepper, and dried oregano. Stir well to coat everything in oil and seasoning.
- saute · ~7 min
Saute until tender-crisp and lightly charred.
Cook, stirring every minute or so, until peppers are softened but still have a slight bite. Look for some dark, blistered spots on the peppers for the best flavor — about 6 to 8 minutes.
TIPResist the urge to stir too often. Let them sit 1 to 2 minutes between turns to develop char. - saute · ~2 min
Add garlic and finish.
Clear a small space in the center of the pan. Add minced garlic and let it sizzle for 30 seconds until fragrant, then stir it into the peppers and onions. Cook 1 more minute.
TIPGarlic burns fast — don't add it until the very end. - serve
Serve hot.
Taste and adjust salt if needed. Transfer to a serving dish and serve immediately while hot.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Slice peppers and onions uniformly so they cook at the same rate.
- 2Use the largest skillet you have to avoid overcrowding and encourage char.
- 3Let the vegetables sit undisturbed for 1–2 minutes between stirs for deep caramelization.
- 4Add garlic at the very end to prevent it from burning and turning bitter.
- 5For extra depth, substitute 1 tablespoon of olive oil with butter halfway through cooking.
- 6Make ahead: reheat in a dry skillet over high heat to restore char, not the microwave.
